Apple's Big Sur Woes See No End As Older Mac Users Report Glitch

Older Macbook Pro computers made by Apple Inc AAPL are getting bricked after their owners apply the latest macOS Big Sur updates, The Verge reported Monday.

What Happened: Laptops that are most commonly affected include late-2013 and mid-2014 models of the 13-inch MacBook Pro, according to The Verge.

The issue reportedly involves a black screen during installation, which is not user-fixable.  The issue was first noticed by MacRumors, which made references to Reddit posts of users who were asked by Apple to bring in their machines for repair. 

“I have a late 2013 MacBook Pro 13. Tried updating to Big Sur and noticed that after some progress bars the screen turned black,” a user wrote on Reddit. “Screen turns on, but there's no chime, fans don't spin and [I] can't get into recovery nor internet recovery. Tried resetting the NVRAM, SMC, connecting to an external monitor, nothing works.”

Why It Matters: Demand for the latest version of macOS has slowed down the Cupertino, California-based tech giant’s servers, The Verge noted.

Users of Big Sur have also reported issues related to opening third-party applications on their computers due to a security feature called “Gatekeeper,” while others express privacy concerns.

The Tim Cook-led company has laid out the steps it intends to take to fix the glitches affecting macOS over the course of the next year.

Price Action: Apple shares closed nearly 0.9% higher at $120.30 on Monday and fell 0.33% in the after-hours session.
